Press Release

Total Phase releases Aardvark I2C/SPI Host Adapter Version 2.0

SUNNYVALE, CA - December 1, 2003 - Total Phase is proud to announce the release of version 2.0 of the Aardvark™ I2C/SPI Embedded Systems Interface.

New in version 2.0 of the Aardvark I2C/SPI Host Adapter:

  • Free GUI Application, the Aardvark Control Center, makes it easy for developers to access the full power of the Aardvark adapter.
  • General Purpose IO, or GPIO, allows the use of the I2C and SPI pins for getting and setting custom signals.
  • Extended I2C features, now supporting 10-bit Slave Addressing, Combined Format transactions, and Repeated Start.

Total Phase has made the Aardvark I2C/SPI Host Adapter even easier to use with version 2.0. It is no longer necessary to develop custom software to use the Aardvark adapter - Total Phase has done the work for you. The Aardvark Control Center software provides easy access to all features of the Aardvark adapter. Within minutes, developers can make full use of I2C, SPI, and GPIO functionality. Thanks to USB, multiple Aardvark adapters can easily be used at the same time, providing a virtually unlimited number of configurations to help engineers develop and test their embedded systems. Best of all, the software is freely available through the Total Phase website.

"The Aardvark Control Center provides an intuitive interface to the powerful features of the Aardvark I2C/SPI Host Adapter," says Kumaran Santhanam, lead engineer for Aardvark products. "Even the most complex operations are just a few mouse clicks away. We've listened to our customers and have endeavored to make the functionality of the Aardvark adapter easily available to all engineers. The Aardvark I2C/SPI Host Adapter is an excellent addition to the tool chest of any embedded systems developer."

Version 2.0 introduces General Purpose IO, or GPIO, which expands the capabilities of the Aardvark I2C/SPI Host Adapter beyond its competition. The I2C and SPI pins can be re-purposed to get and set custom signals on a target system. In addition, engineers can combine GPIO functionality with I2C or SPI, so that they can manipulate pins on their test systems while using I2C or SPI simultaneously to communicate with the target. By integrating all of this functionality into a single unit, Total Phase aims to reduce the number of tools needed to test an embedded system, without sacrificing capability.

Also in version 2.0, the Aardvark I2C/SPI Host Adapter now supports the full breadth of I2C functionality: 10-bit Slave Addressing, Combined Format transactions, and Repeated Start capabilities have been added to the roster of I2C features.

As always, the clean and straightforward API is a hallmark of the Aardvark I2C/SPI Host Adapter. All new features, including GPIO and extended I2C, are supported in the latest version of the Aardvark API so that developers can take advantage of the power of the Aardvark I2C/SPI Host Adapter in their own software. Most importantly, the API is fully supported on both Linuxand Windows and is royalty-free.

Our existing customers have not been left out. If you have already purchased an Aardvark I2C/SPI Host Adapter, then all of these features are available at no extra change. Simply download the new firmware, software, and GUI application from the Total Phase web site and upgrade your Aardvark adapter to version 2.0 to enjoy all of these new features.

About the Aardvark I2C/SPI Embedded Systems Interface

The Aardvark I2C/SPI Embedded Systems Interface is a fast and powerful I2C bus and SPI bus host adapter that operates over USB. It allows a developer to interface a host PC to a downstream embedded system environment and transfer serial messages using the I2C and SPI protocols. I2C and SPI capabilities can be used concurrently.
